SpaceX just brought the crashed booster back, aboard ASOG ...
Or perhaps I should say they brought back half of it. The bottom half, which is fortunate. If any clues as to what happened survived the fire, that’s where they’ll be.
Looked like they had a leak of either TEA-TEB or the landing hydraulic fluid there was blue green flames not the typical color of Kero/LOX. The first fluid burns green for sure.
